24 Royalty-Free Audio Tracks for "Ir Sweep"

Impulse response of a large concrete stairwell in an industrial shopping center. Use this file in conjunction with "stairwell 1 (xy stereo). Wav" for a 4 channel surround recording. You can deconvolve all these recordings with the original sweep file in this pack. Happy deconvolving!.

This audio is not a sound effect itself, however it can be used with an impulse response plugin to recreate the acoustics of a particular environment. This particular file is designed to replicate the acoustics of distant muffled club or rave. This was done using the "profiler stereo lsp plugin" and placing the microphones on the opposite corner of the speaker in a highly reverberous house forcing the audio to reverberate around a corner. After this, a low frequency boost was applied in post along with other general cleanup of the audio.

This is a collection of "small room reverb" impulse responses that i sampled in a new england home known as butternut lodge, built and owned by actress bette davis back in 1940. It consists of all wooden rooms with many non-parallel surfaces, rugs and furniture and includes 3 round-shaped "silo" rooms! these rooms sound clean and do not have the irritating "ping" of many rectangular rooms. Short history/pictures of butternut (https://www. Airbnb. Com/rooms/24692769?source_impression_id=p3_1659215694_liuasyfxoceab5fn). Although these round shapes (and some of the other very small rooms) could potentially wreak havoc with phase at specific frequencies when summed to mono, i recorded this using the mid/side mic technique; therefore, the "side" channels fully cancel out, leaving a clean monaural reverb signal. These irs are stored as flac files. They can be used directly by any daw without conversion and have the added feature of being id3 tagged with a photo of the room each ir is taken from. After downloading, select view -> large icons in the folder to view the rooms. I sampled each room using a swept sine wave into a jbl flip 6 bluetooth speaker; recorded through a tascam tm-st1 m/s stereo microphone, feeding a tascam dr-07 recorder @ 24-bits 44. 1 khz and deconvolved using reaper. As of this post, i've been using these rooms for about 2 weeks. So far, i've found the "garage" to sound fantastic on drums! the drum sound! also, many of the other smaller rooms have a great effect on guitars, keys, and hand percussion. Each room varies in tone and brightness, so i've found that selecting/tuning the reverb send works well if approached like an eq. Increase the effect send until the instrument "feels" right (then perhaps back off slightly). A close-miked acoustic guitar, for instance, will take on a nice brightness and 3-d quality; not particularly reverberant, just big. At that point, i recommend applying any eq, compression, and bigger-sounding reverb effects. Hopefully you enjoy this. Please let me know how you like it and if you have any suggestions. Cheers!.

Peaky noise sweep, using resonant band pass filters then a sharp cut tail.

My roland jupiter 4 with resonance cranked up and filter modulated with lfo by a very low rate. The deep basses at the end of each sweet may be great for deep dub-basses. The sweep sounds great with effects and when gated. Have fun. . .

A sweeping / rising sound, intended for use in build-ups or transitions in dance music. Created with crescendo by digital dj tools: http://digitaldjtools. Net/software/crescendo/.

Warning! loud noise! this sound is not intended to listen to, but to do technical measurements!. This is a test recording i made to measure my headphone's frequency response. It plays a nice "left" and "right" to determine the channels. Then it plays back white noise first in both channels, then one at a time. Then the same with sine sweeps. Then short impulses.

A drone sound i created using a dsi mopho, recorded in logic. I didn't use any fx. It's a filter sweep with some resonance and lfo 1 is modulating pan position.

A 100 bpm synth perc loop, first without and then with a bandpass with its cutoff on a 3-bar sine lfo.

A fast building white noise with added filter sweep and fade-out, layered with a pulsating synthesized bass tone with a slow attack and an affected decay.

I made this as a strange wake-up alarm. I was wondering at what point i will wake-up? what frequency will break my dream and bring me back on earth?. Created using audacity.

Made with music maker's digital keyboard and dn-1 virtual synthesizer. A deep, dark, foreboding sound with a pinging signal sound in the background.

Heavy kick with a low frequency slide. Classic dance music phrasing fx for chorus to build/break transitions. [format: wav][license: cc 0].

Impulse response recorded in the mediterranean conference centre. Valletta, malta. In the knights hall. A medieval hospital used by the crusaders. Main concert venue was too impractical to record an ir but the long cavernous knights hall was empty so hey. . . Let's sweep. .

Impulse response generated from field recordings of a parking garage. Recorded using an audio technica bp4029 m/s shotgun microphone into a zoom h4n recorder. This recording is part of a pack of impulse responses comparing different recording and post-processing techniques. A full explanation of the experiment and recording process is presented in this video: https://youtu. Be/nm65zx3u7me. Sweep recordings were deconvolved using voxengo deconvolver.

Ir recorded in a uk red telephone box. Originally recorded with a full sine sweep but uploaded as a processed spike. Some nasty stuff around 280/300hz but hey, that's a phone box for ya. .

Playing around with the excellent tuner at http://websdr. Ewi. Utwente. Nl:8901/. The website even has a recording button! this version is the same as "shortwave-sweep-and-beeps. Wav" except here i have limited it with a threshold of 10db, which decreases dynamic range but also makes it louder overall.

These sci-fi synth sweeps were created by manipulating white noise with filter sweeps and other effects and then using noise reduction to remove the underlying white noise. You would need to pick through them and cut them up, but they can be useful for sound designing light graphic elements that move around and animate on and off.

Siren effect with digitally controlled frequency sweep using 96khz crystal controlled oscillator, 8-bit binary counters set up as a variable frequency divider. I added slight reverb.

This is a recording of myself sleeping, beginning ~ 1:00 am local time (~ 3hrs after going to bed) on january 10th, 2020 (which i later discovered was a full moon). I was in the midst of experimenting with recording myself all night long out of curiosity, using a laptop placed near the head of my bed. This particular recording was the only anomalous one (the rest consisting mostly of just breathing or snoring with occasional sleep-talking). This ~2 hour recording has several interesting properties, which make it hard for me to believe that these sounds were actually going on while i was sleeping. On the other hand, i don't have a memory of editing this file if i did. Either way, i find it unsettling. I found the file in oct 2021 while organizing my samples. As far as i can remember, this is the original raw recording. On further inspection, i discovered that it has some additional peculiar properties that make it even harder to believe i could have made it without remembering doing so. The audio spans almost exactly 118min (7080s). There’s a frequency sweep with a cycle-length of 6480ms that repeats throughout the entire recording. Dividing the 118min by 6. 48min (60 cycles) results in 18 parts containing exactly 60 cycles and a remainder of 12 cycles. If you think you know the source of the strange sounds or if you've ever heard anything similar, please let me know in the comments or email me at storyofthelie@protonmail. Com.

Very strange sounds from a very high frequency.

Radio motorola.

Lofi radio sound recorded with 3 eur cheap radio unit. Recorded with tascam dr-22wl. ---in case you use any of my sounds, i will be happy to be informed, although it is not necessary. Recorded in 2018.

Layered synthesis of the sound of a big hit. 1 layer. Recorded sound of a blow to the pillow (take with a percussion tint)2 layer. Recorded sound of a blow to the pillow (double low kick)3 layer. Recorded sound of a blow to the pillow (variation of a low-kick double with a low pitch and a different attack phase)4 layer. The sound of a low-frequency sweep, like in a synthetic bass drum, obtained on a synthesizer. )an additional layer of metal impact (recorded by me) is not present in all variations of the sound presented. Each layer was subjected to quite extreme compression and equalization. A bit of overdrive is present. Well, convolutional reverb.
